Running either of these ends up corrupting the os.execv args. If we run: ./scripts/nativesdk-intercept/chown -R foo:foo bar The loop here ends up missing the conversion of foo:foo to root:root because it sees sys.argv[0] and assumes that it's the user:group argument and that we should convert that. We end up a os.execv(path, args) that have the following args: ['root:root', '-R', 'foo:foo', 'bar'] As os.execv ignores args[0], we can just populate it with sys.argv[0] and then loop through sys.argv[1:]. As both chgrp and chown would have either flags and USER[:GROUP] next, this fixes the issue.
